Two different reports complaining that having the Wizard steal the
hero's quest artifact is a bad thing. This doesn't change that,
but it does make all quest artifacts become equal targets so that
wishing for other roles' artifacts doesn't offer such a safe way to
have whichever special attributes they provide.
Quest artifacts are actually higher priority targets for theft than
the Amulet. I suspect that probably wasn't originally intended,
but I left things that way. Taking quest artifacts leaves the hero
more vulnerable to future thefts, and once they're gone the Amulet
has priority over the invocation tools.
